Title: Aperture device for electronic camera
Inventor: KONDO SHIGERU
IPC: H04N5/376
Filed: 1989-10-14
Abstract: PURPOSE:To prevent leakage of a smear noise to a charge transfer line in the transfer process of a signal charge implemented succeedingly by a solid-state image pickup element (CCD) by immediately covering an exposure opening with a shield part provided to an aperture plate after laps of a signal charge storage time of the CCD. CONSTITUTION:When pickup is executed, apertures 15-20 having F-numbers F3.5, F4.6, F5.6, F8, F11, F16 corresponding to the result of photometry are inserted to an optical path and the exposure is started as the charge storage by a CCD 5 is started. When the charge storage time elapses, an aperture drive means 6 is active, an aperture plate 8 is displaced, shield parts 8A-8D enter in the pickup optical path in place of the apertures 15-20 used for the pickup and light is shielded to the CCD 5. Thus, the CCD 5 is not irradiated with undesired light after the charge storage time is finished. Thus, leakage of smear noise to the charge transfer line in the transfer process of the signal charge implemented by the CCD 5 succeedingly is prevented.
